300-445 Question 240
Select 4An enterprise network monitoring team has configured an alert to notify them whenever a critical router's CPU utilization exceeds 85% for more than 5 minutes. After simulating a high CPU load on the router, they do not receive any alert notifications. Which of the following steps should they take to validate the alert's configuration and functionality?
- A
Check if the alert threshold and duration settings are correctly configured in the monitoring system.
- B
Verify that the monitoring system has the correct SNMP or telemetry configuration for the router.
- C
Ensure that the alert notification channel, such as email or SMS, is operational and correctly set up.
- D
Confirm that the simulated high CPU load exceeded 85% for at least 5 continuous minutes.
- E
Upgrade the router's firmware to ensure compatibility with the monitoring system.
Show answer and explanation
Correct answers: A, B, C, D
Explanation
To troubleshoot and validate an alert's configuration and functionality, it is essential to confirm the correctness of the alert's threshold and duration settings, verify the monitoring system's ability to collect data from the device, and ensure alert notifications are properly configured. Additionally, it is important to confirm that the specific alert conditions (e.g., CPU utilization exceeding a threshold for a set duration) were met during testing. Upgrading firmware is not relevant unless explicitly required for compatibility.
- A. Correct.
Correct configuration of the alert threshold and duration is critical to ensure the alert triggers when conditions are met. Without this, the alert may not function as intended.
- B. Correct.
The monitoring system needs accurate SNMP or telemetry settings to collect data from the router. Misconfigurations here can prevent the system from detecting the issue.
- C. Correct.
Alerts rely on notification channels to communicate issues. If the email or SMS service is misconfigured or non-operational, alerts will not be received.
- D. Correct.
If the simulated CPU load did not exceed 85% for 5 continuous minutes, the alert would not trigger. It is important to confirm the simulation met the criteria.
- E. Incorrect.
Upgrading the router’s firmware is not necessary unless there is a known compatibility issue with the monitoring system. This is unlikely to be the root cause in this scenario.
